Abstract: Detection and prevention of resource drain from unauthorized wireless device connections is provided. Responsive to receiving of a connection request from a connecting device, a pre-authentication message is sent to the connecting device, the pre-authentication message including a challenge value. A vehicle hash result is computed using a hash function taking the challenge value and the unique identifier of the vehicle as inputs. A device hash result is received from the connecting device. Responsive to a match of the vehicle hash result and the device hash result, additional hardware of the vehicle is activated to perform a secondary authentication of the connecting device. Responsive to a mismatch, authentication of the connecting device is rejected without activation of the additional hardware, thereby avoiding key-off load from the additional hardware in instances where pre-authentication of the connecting device fails.

Abstract: A system for a vehicle includes an input device configured to send an activation signal responsive to an input to start the vehicle. The system further includes a vehicle body controller, programmed to, responsive to the input and a lack of presence of a phone operating as a key, send an activation signal to activate a power source within a cabin of the vehicle for up to a predefined time period since a last vehicle start.

Abstract: A computer-implemented method includes predicting, via a predictive analytical model, a time interval associated with a future key-on event for a vehicle. The predictive analytical model is based at least in part on key-on event data. The method includes generating, based at least in part on the predicted time interval, a power mode instruction configured to cause a vehicle Telematics Control Unit (TCU) or Phone as a Key (PaaK) system to change a TCU state from a low energy state to a higher energy state, and transmitting, based on the predicted time interval, the power mode instruction to the vehicle TCU.

Abstract: A first computer is connected to a communication network and is assigned a first network address on the communication network. A second computer is connected to the communication network and is assigned the first network address on the communication network. A first message, including the first network address and a request to generate a random number, is transmitted by the first computer via the communication network. A first reply message, including the random number, is received from the second computer in response to the request. A second network address is assigned for the second computer by the first computer based on the random number. A second message, including the second network address and the random number, is transmitted by the first computer via the communication network.

Abstract: The present disclosure includes a system for re-establishing a Bluetooth Low Energy (BLE) pairing PIN key to repair a secure connection between a mobile device and vehicle. The system may detect an error state, and provide a prompt to the user to determine if they wanted to intentionally remove their account. Responsive to an affirmative response from the user that the removal of the connection credentials was intentional, the system may send a revoke request to a server associated with the vehicle. Responsive to a user input that indicates that the removal of the credentials was unintentional, the vehicle may fetch an encrypted PIN seed of the BLE pairing PIN from memory or request the PIN seed from the server. The PIN seed re-establishes the secured pairing of the mobile device and the vehicle infotainment system without undergoing a new device setup procedure.

Abstract: A controller may implement a key delivery manager on the vehicle side to aid in control of consumer access key delivery. These controls may include, for example, key redelivery to a mobile device, choosing a type of key delivery according to availability of vehicle connectivity, and revoking keys according to availability of vehicle connectivity. By using the key delivery manager, the controller takes into account state knowledge as well as connectivity availability to dictate which delivery method (and subsequent user interactions) should be utilized.

Abstract: Exemplary embodiments described in this disclosure are generally directed to systems and methods for securely creating passwords for performing various keyless operations upon a vehicle. In an exemplary method, a computer receives a request for creating a password for a phone-as-a-key (PaaK) device. The computer determines that the PaaK device is present inside the vehicle and that the vehicle engine has been placed in an accessory state or a run state by an authorized PaaK device located in the vehicle. The computer further determines that a passive entry passive start (PEPS) key fob is present inside the vehicle. A prompt is provided for entry of a password. The computer checks to determine if an entered password has been already assigned to another PaaK device. If unassigned, the computer links the password to the PaaK device and authorizes the entered password as a valid keyless starting password for the vehicle.

Abstract: Exemplary embodiments described in this disclosure are generally directed to systems and methods for ensuring password security when starting a vehicle having a keyless engine starting system. In an exemplary method, a computer detects a depression of an engine start push button when no phone-as-a-key (PaaK) device or passive-entry-passive-start (PEPS) key fob is present in the vehicle. The computer responds by executing a verification procedure prior to password validation. The verification procedure can include operations such as determining that no PaaK device or PEPS key fob is present either inside the vehicle or within a defined geofence outside the vehicle. If the verification procedure is successful, the computer displays a prompt upon a display screen for entering of a password. The computer then uses various security measures when verifying the validity of an entered password, followed by displaying of a message indicating acceptance or rejection of the password.
